Cerulean is offered as a subscription based service. What that means is that you purchase a subscription that is valid for a
certain duration (an year or a month depending on what kind of subscription you purchased). During that duration, you are eligible
for free upgrades and support. If you have activated your subscription via a license key, you must purchase a new license key once
your subscription expires. If you have activated your subscription directly, the subscription will be automatically renewed once the
subscription duration has expired.
